【方歌】百会疽在巅顶结，经属督脉百会穴，初如粟米渐如钱，
甚似葡萄坚似铁。高肿热实清毒火，平塌阳虚温补怯，
肿连耳项动痰声，七日不溃命必绝。
【注】此百会疽，又名玉顶发，生在巅顶正中，属督脉经百会
穴。由膏梁太过，火毒凝结而成。初起形如粟米，渐肿
根大如钱，甚则形似葡萄，坚硬如铁，高尖红肿，焮热
疼痛，疮根收束，憎寒壮热，大渴随饮随干，口苦唇焦
，便秘烦躁，脉见洪数者，此属气实。宜服黄连消毒饮
，以清毒火，外敷冲和膏，若漫肿平塌，紫暗坚硬，〔
兴月〕痛根散，恶寒便泻，脉见细数者，此属阳虚宜服
十全大补汤，以温补之，外敷回阳玉龙膏。若面赤过烦
，口干不渴唇润者，此属阳虚浮泛，宜服桂附地黄丸，
引火归源，更用生附子饼，置两足心涌泉穴，各灸五壮
，以泄其毒。初起贴琥珀膏，已溃参黄灵药，太乙膏盖
贴；腐尽，再易生肌之药治之。若肿连耳项，痰如拽锯
，七日无脓不溃，神昏者命必绝矣。

【方歌】百会疽发生在头顶部位，归属于督脉的百会穴。初期症状像粟米大小，逐渐扩大如铜钱，严重时形状像葡萄，质地坚硬如铁。若表现为高起肿胀、热象明显且属实证，应清解毒火；若表现为平塌凹陷、阳气虚弱，则需温补怯弱。若肿胀蔓延至耳部和颈部，伴有喉间痰鸣声，七日不溃破则性命必绝。
【注】这种百会疽，又名玉顶发，生于头顶正中，属于督脉经的百会穴。由饮食过于肥甘厚味，导致火毒凝结而成。初起时形状如粟米，逐渐肿胀，根部宽大如铜钱，严重时形状似葡萄，坚硬如铁，高高隆起红肿，灼热疼痛，疮根收束，憎恶寒冷且高热，极度口渴，喝水后立即感到干燥，口苦唇焦，便秘烦躁，脉象洪数，这属于气实（实证）。适宜服用黄连消毒饮，以清解毒火，外敷冲和膏。如果漫肿平塌，颜色紫暗坚硬，[兴月]痛处根部散漫，恶寒便泻，脉象细数，这属于阳虚。适宜服用十全大补汤，以温补身体，外敷回阳玉龙膏。如果面色赤红过度烦躁，口干但不渴、嘴唇湿润，这属于阳虚导致的虚火浮泛，适宜服用桂附地黄丸，以引火归源，另外用生附子饼，放置在两足心的涌泉穴，各灸五壮，以泄出毒邪。初起时贴琥珀膏，已溃破后使用参黄灵药，太乙膏覆盖贴敷；腐肉排尽后，再更换生肌药物进行治疗。如果肿胀连接耳项，痰声如拉锯，七日无脓且不溃破，神志昏迷者，性命必绝。

[Prescription Verse] Baihui Jū (Baihui Carbuncle) occurs at the vertex, belonging to the Du Meridian's Baihui Acupoint. Initially resembling a millet grain, it gradually enlarges to the size of a coin; severely, it resembles a grape and is hard as iron. If presenting with high swelling, heat, and excess syndrome, clear the toxic fire; if presenting with flat collapse and Yang deficiency, apply warm tonification. If the swelling extends to the ears and neck with phlegm rattling in the throat, and fails to suppurate within seven days, life will be lost.
[Annotation] This Baihui Jū, also known as Yuding Fa (Jade Top Eruption), arises in the center of the vertex and belongs to the Baihui Acupoint of the Du Meridian. It is caused by excessive consumption of rich and greasy foods, leading to the coagulation of Fire-Toxin. Initially, the shape resembles a millet grain; it gradually swells with a root broad as a coin. Severely, it resembles a grape, hard as iron, rising sharply with redness and swelling, burning heat, and pain. The base of the sore is gathered, accompanied by aversion to cold and high fever, extreme thirst where drinking provides immediate relief from dryness, bitter taste in the mouth, scorched lips, constipation, irritability, and a flooding and rapid pulse. This indicates Qi Excess (Excess Syndrome). It is suitable to take Huanglian Xiaodu Yin (Coptis Decoction for Clearing Toxicity) to clear toxic fire, and externally apply Chonghe Gao (Harmony Plaster). If there is diffuse swelling with flat collapse, purple-dark color, hardness, [Xingyue] pain with a scattered base, aversion to cold, and loose stools, with a fine and rapid pulse, this indicates Yang Deficiency. It is suitable to take Shiquan Dabu Tang (Ten Substance Great Tonifying Decoction) to warm and tonify, and externally apply Huiyang Yulong Gao (Return Yang Jade Dragon Plaster). If the face is overly red with severe irritability, dry mouth but no thirst, and moist lips, this indicates floating false fire due to Yang Deficiency. It is suitable to take Guifu Dihuang Wan (Cinnamon and Aconite Rehmannia Pill) to guide fire back to its source. Additionally, place raw Fuzi Bing (Aconite Cake) on the Yongquan Acupoints (KI1) of both soles, moxibustion five Zhuang each, to vent the toxin. At the initial stage, apply Hupo Gao (Amber Plaster); after ulceration, use Shenhuang Lingyao (Ginseng and Yellow Calomel Medicine), covered with Taiyi Gao (Supreme Emperor Plaster); after necrotic tissue is completely eliminated, change to flesh-generating medicines for treatment. If the swelling connects to the ears and neck, phlegm sounds like sawing, no pus forms and does not ulcerate within seven days, and consciousness is clouded, life will be lost.
